Help with Maps[edit]

I am co-creating a world, and have no artistic ability to speak of. I can't draw a straight line with a ruler. However, i need a way to design a world map, i understand continent formation, and even ocean currents to some degree, so if i can get a program with tiles, or hexs, i think i can make one myself, does anyone know of any editors like this? --Ganre 05:06, 8 May 2008 (MDT)
